Abstract
A method for reducing hysteresis error and high frequency noise error of capacitive tactile sensors includes the following steps: stepcalibration, specifically including positive stroke calibration to form n positive stroke curves and negative stroke calibration to form n negative stroke curves; stepaveraging, specifically including positive stroke averaging to form an average positive stroke curve, negative stroke averaging to form an average negative stroke curve, and comprehensive averaging to form a comprehensive stroke curve; stepfitting modeling, to obtain a positive stroke fitting function, a negative stroke fitting function, and a comprehensive fitting function; stepmeasurement; stepnoise filtering; stepstroke direction discrimination; and stepresolving, to obtain the force at the current time by using a corresponding fitting function based on the stroke direction discrimination result.
